Infrared photometry and spectroscopy of the supersoft X-ray source RX J0019.8+2156 (= QR And).

QUAINTRELL H. and FENDER R.P.

Abstract (from CDS):

We present JHK photometry and spectroscopy of RX J0019.8+2156. The spectrum appears to be dominated by the accretion disc to at least 2.4µm, over any other source of emission. We find Paschen, Brackett and He II lines strongly in emission, but no He I. There are satellite lines approximately 850km/s either side of the strongest, unblended hydrogen lines. These satellite lines may be the spectral signature of jets from the accretion disc.
